Types of Bed Bases: Divan, Slatted, Ottoman and Adjustable
Posted by Tom Hughes on
The main types of bed base are platform-top divans, sprung divans, slatted bed frames, ottoman storage bases and adjustable beds. Each option can affect how your mattress feels, how much storage you have and how much space the complete bed occupies.
Choosing a base is therefore about more than appearance. You should also consider mattress compatibility, bedroom dimensions, storage requirements and whether you prefer a firmer or more responsive sleeping surface.
Types of Bed Bases at a Glance
| Base type | Typical feel | Storage | Main consideration |
|---|---|---|---|
| Platform-top divan | Stable and generally firmer | Drawers or ottoman options | Check mattress compatibility |
| Sprung divan | More responsive and cushioned | Selected drawer options | Usually costs more than a platform top |
| Slatted bed frame | Depends on rigid or sprung slats | Usually open underneath | Check slat spacing and mattress requirements |
| Ottoman base | Depends on the supporting surface | Large enclosed compartment | Requires space and suitable access for lifting |
| Adjustable base | Changes with the selected position | Usually limited | Requires a flexible, compatible mattress |
Divan Bed Bases
A divan is an upholstered base designed to support a mattress without a separate surrounding bed frame. Divans are compact because their external dimensions are normally close to those of the mattress, making them practical in smaller bedrooms.
They are available in numerous fabrics and can be paired with a coordinating headboard. Many also include drawers or lift-up storage. You can explore our current bed bases and headboards online.
Platform-Top Divans
A platform-top divan has a rigid, non-sprung upper surface. This normally creates a stable and slightly firmer feel beneath the mattress. It is a popular, practical choice and can often be ordered with storage drawers.
Sprung-Edge and Firm-Edge Divans
A sprung-edge divan contains springs within the base, providing an additional responsive layer beneath the mattress. It can create a more cushioned feel and is often used as part of a premium complete bed.
A firm-edge divan combines a sprung area with firmer support around the perimeter. Exact construction varies between manufacturers, so it is worth comparing the complete bed rather than choosing by the base description alone.
Slatted Bed Frames
Wooden, metal and upholstered bed frames commonly support the mattress using either rigid or sprung slats. Rigid slats provide a stable surface, while curved sprung slats can add a small amount of flexibility.
Always check the distance between the slats. Gaps that are too wide may not adequately support some foam, pocket-sprung or heavier mattresses and could affect the manufacturer’s guarantee. A central support rail and additional supporting legs are particularly important on wider double, king and super king frames.
Bed frames can also be wider and longer than their mattress. Measure the complete external dimensions, especially when choosing a frame with a substantial headboard or foot end. Our UK mattress size guide explains the difference between mattress dimensions and the space required by the finished bed.
Ottoman Bed Bases
An ottoman base lifts to reveal a large enclosed storage compartment beneath the mattress. Because most of the internal base can be used, an ottoman generally provides more storage than a divan with drawers.
Ottoman beds may open from the side or foot end and are normally assisted by a lifting mechanism. Consider the room layout before choosing: you need suitable access to lift the base and reach the compartment comfortably.
The supporting surface may be a platform top or slatted frame, depending on the model. Browse our ottoman beds for examples of complete storage beds.
Adjustable Bed Bases
An adjustable bed uses a powered base to raise or lower selected areas beneath the mattress. Elevating the head can make reading or watching television more comfortable, while raising the leg section may help some users find a more comfortable resting position.
These bases require mattresses that are flexible enough to follow the movement without damaging their internal construction. Adjustable beds can also use specialist dimensions, so an ordinary replacement mattress should not be ordered without checking compatibility.

Does a Bed Base Affect How a Mattress Feels?
Yes. A rigid platform top generally makes a mattress feel slightly firmer and more stable, while a sprung base can add responsiveness. Slat type, slat spacing and the condition of an older base can also influence support.
For this reason, a mattress tried on one type of base may feel different when placed on another. If you are keeping an existing base, tell the retailer which type you have and check that it remains supportive, level and compatible with the new mattress.
Can You Put Any Mattress on a Divan Base?
Many mattresses can be used on a platform-top divan, but compatibility should never be assumed. Some mattresses are designed as part of a matching bed set, while others have specific ventilation or support requirements. Always check the manufacturer’s guidance, particularly if retaining an old base.
Which Bed Base Is Best?
The best bed base depends on what matters most to you. Choose a platform-top divan for compact dimensions and stable support, a sprung divan for a more responsive complete bed, a slatted frame for a more decorative design, an ottoman for maximum storage or an adjustable bed for positional flexibility.
